How many dragons can be found in the game of DAO?

Summary:Discover the game of DAO and the Quest for the Golden Dragon, which involved players searching for vulnerabilities in the smart contract code. At least four major dragons were found and exploited by a hacker, leading to the theft of millions of Ether.

How many dragons can be found in the game of DAO?

DAO, or Decentralized Autonomous Organization, is a blockchain-based organization that operates through smart contracts. One of the most famous DAOs was The DAO, which raised over $150 million in Ethereum during its initial coin offering (ICO) in 2016. However, The DAO was hacked, and a significant amount of funds were stolen, leading to a hard fork of the Ethereum blockchain.

One of the most interesting features of The DAO was its game-like structure. Players could purchase tokens in The DAO and then use those tokens to vote on proposals for how the funds should be used. The more tokens a player owned, the more voting power they had.

One proposal that gained a lot of attention was the creation of a game within The DAO called "The Quest for the Golden Dragon." The game involved players searching for "dragons" within The DAO's smart contract code. Each "dragon" was essentially a vulnerability that could be exploited to steal funds from The DAO.

So, how many dragons were there in The DAO? The exact number is difficult to determine, as new vulnerabilities were constantly being found and patched. However, it is estimated that there were at least four major dragons that were exploited by the hacker who stole funds from The DAO.

The first dragon was a reentrancy bug in The DAO's split function. This bug allowed the hacker to repeatedly withdraw funds from The DAO without the smart contract updating the hacker's balance. The hacker was able to steal over 3.6 million Ether (worth over $50 million at the time) using this exploit.

The second dragon was a recursive call bug in the same split function. This bug allowed the hacker to trick the smart contract into sending a large amount of Ether to an address it believed was a DAO contractor, but was actually a child DAO the hacker had created. The hacker was able to steal an additional 1.5 million Ether using this exploit.

The third dragon was a "timestamp dependency" bug in the same split function. This bug allowed the hacker to manipulate the Ethereum network's timestamp to ensure that their transaction was processed before other transactions, giving the hacker an advantage in exploiting the reentrancy and recursive call bugs.

The fourth dragon was a vulnerability in the way that The DAO's voting system worked. The hacker was able to use a "split proposal" to create a child DAO and transfer funds to it without the necessary number of votes. This vulnerability was not technically a "dragon" within the game, but it still allowed the hacker to steal funds from The DAO.

In conclusion, The Quest for the Golden Dragon was an intriguing game within The DAO that highlighted the importance ofsmart contract security. The DAO's failure ultimately led to the creation of Ethereum Classic, and it serves as a cautionary tale for blockchain projects that prioritize fundraising over security.

Investors in cryptocurrency should always be aware of the potential risks and vulnerabilities in the projects they invest in. This includes understanding the security measures in place, reviewing the code for potential vulnerabilities, and keeping up-to-date on any news or developments that could affect the project's value. Additionally, investors should consider diversifying their portfolio and not putting all their eggs in one basket.
